Acoustic Emission Hit Generation Behavior of Basalt Fiber High Strength Mortar under Compression

Abstract:

Acoustic emission (AE) has been applied to study the fracture mechanics of concrete and other cementitious materials. In this paper, the AE hit generation behaviour is employed to investigate the fracture of high strength mortar containing basalt fiber under compression. A variety of amount and length of basalt fiber were used in mortar mix. Result shows that there is no significant effect observed on behavior of AE hit generation due to the differences amount and length of basalt fiber in mortar. All indicates the similar behaviour that can be described into three stages. At the second stage when maximum load starts to occur, AE hits are generated significantly indicating nucleation of many cracks. Materials failure in ductile manner since AE activities still can be recorded at long after post peak behaviour.
